Machine Problem 1: Hello World

Out: Monday, January 7, 2008

Due: Tuesday, January 15, 2008 In this machine problem, you will familiarize yourself with the VMware client and your private network of machines.

1. If you are not already subscribed to the csg712 mailing list, subscribe yourself by going here. Be sure to include your first and last names, so I'll know who is who.
2. If you did not submit a picture for the CSG711 gallery last semester, submit your picture for the picture gallery. The instructions are here.
3. Your cluster will consist of a "server machine" and some number of "client machines". The server has two NICs: eth0, which will communicate with the outside world, and eth1, which is used for communication between the server and the client machines. Get your server machine and at least one client machineinto a state where it is usable for the remainder of this machine problem.
4. On your server, set up a TCP echo server. This is a program that will accept a connection from a client application, receive one line of text, echo that line back to the client and close the connection.

   You also needn't worry about shutting down the server remotely. But do make sure you arrange things so that you can shut down the echo server by going to the server machine and doing a kill -9 or something of the like.

   To test your server, go to one of your client machines and telnet to the server on this port. You may do this in any language you like. If you get your code from the web, please indicate the source and any modifications you made, and make sure you understand it in detail.

5. On one of your client machines, set up an echo client that will take some input and send it on to the echo server. Do this in a language other than the one you wrote the server in. The notes above about attribution hold here, too.
